Make Horizon work on centos+binary

Several problems exist with Horizon on centos+binary:

1. The default setup of http binds a port to port 80 on RPM
   based distros.

2. There is no horizon user/group added causing config-external
   to break badly.

3. openstack-dashboard is installed in
   /usr/share/openstack-dashboard/openstack_dashboard. This
   is incompatible with the expectations of the wsgi configuration.

4. the target for config-external is
   /etc/httpd/sites.d/horizon.conf. It should be
   /etc/httpd/conf.d/horizon.conf

5. A workaround is required for:
    https://bugzilla.redhat.com/show_bug.cgi?id=1220070

6. Static display requires compressing the installation via
   manage.py.  To do this correctly pyscss needs to be upgraded
   because the version in RDO is broken.
